Look, if you want to play semantic games, I'll bite.
The fact that Jack is dead is consistent with either conclusion, so in a program of piling up facts consistent with a hypothesis, then Jack's pining-for-the-fjords would constitute part of that pile.
But in real world cases, we look for facts which exclude competing hypotheses, otherwise our pile of "evidence" starts to include all sorts of irrelevancies.
For instance, the fact that the sun rose today is consistent with Alice having killed Jack, and also consistent with Bob having killed Jack. Apparently you'd say that the sun's appearance in the sky is evidence of both conclusions. I think most people understand that the sun is (so far as we can tell) irrelevant to deciding which of the two hypotheses is true. Similarly, the fact that Jack is dead offers us no help in determining if Alice killed him, or Bob killed him, or if you or I did.
Now, are you merely being pedantic troll, or are we disagreeing on some real issue?
If the sun hadn't risen today, what effect would that have on the hypothesis that Alice killed Jack?
If Jack walks into the room alive, what effect would that have on the hypothesis that Alice killed Jack?
I think that your analogy is flawed.
